Chemistry (12)The Chemistry Department is developing major enhancements to the general education chemistry courses, for both science majors and non-science majors. The enhancements focus on two topical areas, forensic chemistry and environmental chemistry, and include the addition of guided inquiry laboratory experiments using GC/MS. The project addresses several related needs: an applications oriented real life context for learning, and the use of direct active involvement pedagogies. New forensic and environmental experiments are being developed (and some also are being adapted from existing materials) for several courses, using the active inquiry experimental framework. These new experiments focus on using a GC/MS equipped with an autosampler and theestablishment of a remote data analysis site to allow regular use by laboratorysections of 18-24 students per section. Twelve experiments (four adapted from published works, eight new) are being developed, including two service learning experiments. The project also includes an outreach component, consisting of a series of workshops for area high school teachers. Workshops are providing hands-on experience with modern instrumentation, including GC/MS, NMR, AA, and FTIR, as well as emphasizing inquiry based experimentation, real-life applications, and service learning projects. The project is informed by the ongoing curricular revision process at Roanoke College. The unifying vision is an "Essential Questions" model for all general education classes, with active inquiry being emphasized in every General Education course. Introductory science courses for both majors and non-majors are being re-structured within this model, emphasizing current applications, current questions, and modern approaches. The intellectual merit of the project includes the development of new curricular materials bringing important real life applications into the laboratory experience of both science majors and non-majors. The new and adapted experiments are uniquely suited to the general education setting and include appropriate active learning pedagogies. Secondary benefits also result from the use of the GC/MS in upper level courses and undergraduate research. Broader impacts of the project include the dissemination of the curricular materials developed, workshops for high school teachers, and the improvement in the scientific education of many young citizens, both science majors and non-science majors. Each year, approximately 400 students are being impacted by the revised laboratory courses, and 24 high school teachers are participating in the workshops.

化学（12）化学系正在为科学专业和非科学专业的通识教育化学课程开发主要增强功能。增强功能集中在两个局部区域：法医化学和环境化学方面，包括使用GC/MS进行指导的调查实验室实验。该项目满足了几种相关需求：以应用程序为导向的现实生活中的学习环境以及直接积极参与教学的使用。 使用主动查询实验框架，正在开发新的法医和环境实验（有些也从现有材料中调整了一些课程）。这些新实验的重点是使用配备自动采样器的GC/MS和远程数据分析网站的建立，以允许每节实验室定期使用18-24名学生。正在开发十二个实验（四个改编自出版的作品，八个新作品），包括两个服务学习实验。 该项目还包括一个外展部分，包括针对地区高中教师的一系列研讨会。讲习班提供了现代仪器的动手经验，包括GC/MS，NMR，AA和FTIR，并强调基于询问的实验，现实生活应用和服务学习项目。 罗阿诺克学院正在进行的课程修订过程为该项目提供了信息。统一的愿景是所有通识教育课程的“基本问题”模型，在每个通识教育课程中都强调了积极的询问。在该模型中，正在重新结构专业和非议员的入门科学课程，强调当前的应用程序，当前问题和现代方法。该项目的智力优点包括开发新的课程材料，将重要的现实生活应用带入了科学专业和非律师的实验室经验中。新的和改编的实验非常适合通识教育环境，并包括适当的积极学习教学。在上层课程和本科研究中使用GC/MS的次要好处也会产生。 该项目的更广泛的影响包括开发课程材料的传播，高中教师的讲习班以及许多科学专业和非科学专业的许多年轻公民的科学教育的改善。每年，大约有400名学生受到修订的实验室课程的影响，24名高中教师正在参加研讨会。
